Application scope of South Africa origin Foundry grade chromite sand
1. The thermal conductivity of chromium ore is several times greater than that of silica sand, which can increase the cooling rate of castings. Therefore, chromium ore can play the role of an external cold iron in actual applications;
2. In casting production, chromium ore is mainly used as surface sand for large steel castings to prevent sand from sticking to the surface of the castings; secondly, it is ground into refractory aggregate for casting coatings;
3. Adding an appropriate amount of South African chromite sand to the molding sand can be used as surface sand for steel castings and pig iron. Adding an appropriate amount of South African chromite sand to the mixture can effectively prevent welding defects such as thermal deformation.
4. The thermal conductivity of chromium ore is several times greater than that of silica sand, which can increase the cooling rate of castings. Therefore, chromium ore can play the role of an external cold iron in practical applications;
5. The impact of the particle size of chromium ore on its refractoriness. The particle size of chromium ore can significantly affect its refractoriness.
